If you were stranded on a desert island and could only have ONE piece of weight-training exercise gear - what would it be? Personally, I'd choose a SPRI 24lb. Body Bar w/Foam Padding.
4 feet long, dense as heck, and covered with no-slip grip dense foam - it's possible to do a total body workout routine: From deadlifts to squats to curls to presses, from head to toe. Available in weights up to 24 pounds... Oh you don't think that's very heavy? Set a workout timer to 30 minutes and schlep that weight around non-stop till ya puke : You'll get a great work-up-a-sweat work out!
